Thanks for the help. Tar works where cpio didn’t. However, switching from gzip to xz costs 9 extra minutes (10 vs 1) in the packimage step. I couldn’t find a knob to twist to make it use xz -0 or xz -3 rather than the default level -6 compression, and XZ_OPTS was not passed from the environment where packimage was called to the actual xz process.
